A method and apparatus is presented. Layers of composite material are laid down on a forming tool. A respective bend is formed in each of the layers to form the composite filler comprising bent layers on the forming tool. The composite filler comprising the bent layers is placed into a gap formed by at least one composite structure.

An image display including an image substrate and a support structure. The image substrate has an image printed on a first surface. The support structure can include a front sheet and a plurality of side strips extending from the front sheet. The image substrate can be adhered to an external surface of the front sheet so that the front sheet forms a rigid backing for the image substrate. A variety of image substrates are provided.

A method is provided of bonding together at least two parts. The method includes assembling together at least two parts and at least one adhesive layer, the adhesive being configured so that its adhesive power increases on heating as a result of it polymerizing, at least one of the parts being made of composite material or of metal, the adhesive layer being present, after assembly, between the parts, the assembled together parts and the adhesive being present in a chamber defined by a wall, the wall having an inside face situated facing a first part present between the adhesive layer and the wall, the first part being intended to be bonded to a second part and only a fraction of the second part being present inside the chamber; and applying a liquid against the wall on its side opposite from the chamber.
